Roku is a streaming device, it has many channels and TV shows which streams multiple type of content at a time. And thus user doesn't want to search for other channels.
Connecting your Roku device to Wifi is a simple way by just following these steps,

·Then go to settings change your network configuration to Wifi and then choose your required network connection.
·Signup your account with username and password and then login your account with Roku com link.
Remember the password because the wireless network password is more sensitive. If you forgot the password reset your Wifi and clears the error. To activate your Roku device go to Roku.com/link. For further details contact @ +1-844-965-4357.

You will have to either remember your password, or reset your wifi back to factory settings and set up a new password. In order to clear the "code 011" error, you will have to hold the reset button down on the Roku for at least 30 seconds to do a factory reset. But, don't do this until you get your wifi password issue squared away first.

I hope that helps.
